Our invention relatesl torconductorxsupports and more particularly to. conductor.y supports of the character used with `post onpinatype; insulators. Its principal Objectis to provide a'V support which will enable the conductor clamp Atorbe. readily, easily and safely removed from. its mounting under hot line conditions,` that'. is, while current is still flowing through the. conductor, without completely disassembling .thenconductor clamp.

A primary feature offtheinventionf consists in providing a conductor clampwithoppositely projecting pintleswhich are pivotally supported ina mounting from.` which the clamp Ymay be removed without being disassembled@ Another feature ofthe inventionv consistsv in providing a cotter pin. fora lockingthel-.conductor seat in pivotalv associa-tion with the-mounting, the pin having anvoffsetportion normally preventing its removal from themounting. when-.moved-to a.

position permitting the olamptofbe-removed from the mounting.

Another feature of theinvention .consists in arranging the keeper of the. cla-mp which-.is piv otally and removablysupported.. in .a `mounting so that the clamp may notbe removed. from the mounting whenthe'keeperisdn. clamping relation with the conductor..

The pintles 8 and 9A are-formedonaseatmenrber I0 of the conductor clampwhich also-includes a keeper member II.

pintle 9, disconnection of the seat from'thev mounting by axial movementof the seat being prevented by the end wallsA I4 of .the-upstanding portions 6 and 'I of the mounting.

To prevent upward movement ofthe side of the seat having the pintle 9, a cotter pin I5l isemployed for holding or locking the pintle 9 inpivn otal relationship with the mounting..

The cotter pin I5 has two laterally spaced arms or legs I6, one of which. is crimped or otherwise formed with an oifset portion Il intermediate its ends which normally prevents thev cotter. from being moved to unlocking position,.that is to-say, a position in which ther adjacent. pintle 9 of the seat I may be moved upwardly to. disconnect the clamp from the mounting This crimped portion I'I of the cotter pin is so formedwith. respect to the eye or connecting end portion Il! of. the cotter as to be in contiguous relationwiththe inner face of the portion I3. of. the ear 'Iv and it is also formed in such manner. that the legs or. arms of the cotter must be compressed or. forcedI together in order that it may pass through the aper ture in the portion I3. Thus. whenthe cotter is.. moved into locking position, the arms thereof will.V

spring apart after the crimped portion IT passes through the aperture in. the portion I3 andthe tion to permit the clamp to beremoved from the..

mounting. For this purpose, the outerv end. of the upper one of the .arms ofthe cotter pin is formed with. an offset portion. I9 which, when the cotter has been withdrawn. suiciently fromA themounting to permit removal. of. the conductor clamp, engages the. inner face ofthe upper part a0 of the upstanding portion I3. Aswllbe seen. in Figure i, the. innerface. off the.. upper .part 2.9 ,y is spaced. outwardly from .the inner. .face .of .the

cotter will, therefore, be held in locking position.

remainder of the portion I3 so that the outer end of the lower arm of the Cotter will not interfere with the pintle 9 when being raised to remove the clamp from the mounting. The outer end portion of the lower arm of the cotter inclines downwardly as shown in Figure 2 so that, upon rapid movement of the cotter into unlocking position, it will tend to force the outer end portion of the upper end of the Cotter upwardly and thus insure engagement of the offset portion I9 with the upper part 2i) of the portion i3 on the mounting.

One oi the legs of the Cotter pin is preferably maintained in yielding engagement with the adjacent pintle of the clamp seat so as to eliminate possible radio interference which might arise from the pintle vibrating because of vibrations transmitted thereto from the conductor. For this purpose, the upper wall 2| in the aperture in the portion l2 or the mounting is inclined downwardly so that, when the cotter pin is moved into locking position, its arms will be forced toward each other and the lower arm will thus be maintained in yielding engagement with the pintle.

rlhe keeper ii of the clamp is Connected to the seat member l@ for clamping the conductor by a pair of bolts 22 which it will be seen need not be removed to disconnect the Clamp from the mounting. rfhe keeper is preferably formed on opposite faces with portions of different curvature so that merely by reversing or turning the keeper over, it can be used with conductors of widely dilferent diameters.

In the modied form of the invention shown in Figures and 6, both ears or lugs 23 of the mounting t@ for the conductor clamp are formed with apertures 25, instead of one of the lugs or ears having laterally spaced portions as in the form oi' the invention illustrated in Figures l to 4, inclusive. The seat member 2t of the conductor clamp shown in Figures 5 and 6 has oppositely projecting pintles 21 which extend into the apertures 25 of the lugs 23 and the keeper member 28 thereof is of such construction that, when it is secured to the seat member for clamping the Condutor thereto, its outer ends are in such contiguous relation with the inner faces of the lugs 2; that the seat member 2t cannot be moved a suicient distance axially of the pintles 2'! to enable the clamp to be disconnected from the mounting.

To remove the clamp from the mounting, it is, however, merely necessary to loosen the bolts 29, which connect the seat and keeper members together, so that one end of th-e keeper may be raised suiciently above the adjacent lug of the mounting to enable the clamp to be moved axially of the pintles 2l a distance sufficient to withdraw the pintle on the opposite side of the clamp from the aperture in the lug with which it is associated. rThe portion of the Clamp adjoining the pintle which has been withdrawn from its lug is then raised above that lug so that the Clamp can be moved axially of the pintles in the opposite direction to withdraw the other pintle from the other lug of the mounting.

The upper surface of the inner portion of each aperture is preferably inclined upwardly as indicated at Si! to facilitate the withdrawal of the intle which is first removed from the mounting and the lower surface of the outer portion of each aperture is downwardly inclined as indicated at 3l to facilitate removal of the last pintle. By providing the apertures in the lugs with inclined surfaces of the character indicated, lt is not nec- 4 essary to loosen the bolts 29 as much as would otherwise be required. The bolts themselves are, of Course, suiciently long so that the nuts 32 need not be removed from them to permit the keeper to assume a position enabling the seat to be removed from the mounting.

In each form of the invention, it will be perceived that the conductor clamp is formed with oppositely projecting pintles which are pivotally supported in a suitable mounting to enable the clamp to angle suiiciently so that undue strains will not be placed on either the conductor or its support as a result of forces to which the Conductor is normally subjected.
